Have you considered a mural? We make a durable, non-fading material that is seamless up to 5 metres wide on the short side (length can be over 100 metres!). Normally we install it on ceilings, so it is called 'stretch ceiling', but it works just as well on walls, and can be wide-format printed with any high resolution image. A narrow, nearly invisible frame of aluminum supports the material all around the perimeter. Our material also comes in translucent, which we can install with LED lighting behind. Here are some previous installations of ours. Please feel free to browse our profile and add anything that inspires you to your ideabooks! The material and framing is all fully recyclable.

This is my actual wall. I want to put curtains of the sea green colour from the wallpaper. I also needed help with the headboard. Im planning to put a brown velvet fabric, same color as the wood finish on my bed so it almost looks like a part of my bed. I have two headboards, as you can see from the picture. Im planning to do quilting only on the front small headboard and leave the back plain. Please give suggestions! Following are some options of drapes which Im considering but not sure which one will go best. I also have window on the left side of the bed, is it fine to have a normal wooden blind on that window and drapes behind my bed? Thanks!

add a mirror in each niche, use a nice wallpaper behind it and simple curtain blinds will make it interesting. Use a highlight paint on ceiling to match with wallpaper

Thanks for the suggestion, the board on the wall 1 is the headboard(i.e legs toward the wardrobe) mostly. Either side is fine for me.
